Device for the transmission of motion to an oscillating arm of an irrigation device
First Claim
1. A device for the transmission of motion to an oscillating arm of an irrigation device, said arm being rotatably fastened at its ends to a pair of side elements of the irrigation device, from one of which there extends a driving shaft, comprising a cam substantially in the shape of a heart secured to said shaft, a connecting rod coupled to said cam by a pair of shoes that engage the perimeter of said cam in substantially diametrically opposite positions, the connecting rod being provided with a slot wherein a guide for the connecting rod is secured to said cam, and a crank secured to said arm, characterized in that said connecting rod can be hinged to said crank in a plurality of positions substantially aligned along a radial direction lying in a plane orthogonal to the axis of rotation of the arm and placed at different distances from said axis of rotation.

Abstract
An irrigation device has an arm which is rotatably fastened at its ends to a pair of side elements of the irrigation device, and from one of which elements there extends a driving shaft. The device comprises a cam substantially in the shape of a heart integral with the shaft, a connecting rod coupled to the cam by the of a pair of shoes that engage the perimeter of the cam in substantially diametrically opposite positions. The connecting rod is provided with a slot wherein a guide for the connecting rod is engaged integral with the cam, and a crank integral with arm. The connecting rod can be hinged to the crank in a plurality of positions substantially aligned along a radial direction lying in a plane orthogonal to the axis of rotation of the arm and placed at different distances from the axis of rotation.
